PERPETUAL CALENDAR.

'Application filed July 11, 1916.

To all whom it may concern:

Be it known'that I, LURA AMA DA Roo'r, a citizen of the United States, residing at Bloomfield, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Perpetual Calendars, of which the following is a specification.

My invention-relatesto a calendar and its main object is to provide an improved and simplified construction which is capable of perpetual use.

A prime object is to provide a: calendar having a plurality of chronological members one movable relatively to the other so that they may be lt rought into, proper registry according to the date.

Another object is to provide a construction possessing the details which will pres ently appear and which also accomplishes the additional objects and advantages later to be pointed out.

In accompanying drawings illustrating one preferred embodiment Figure 1 is a perspective view of the im proved calendar;

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1, looking in the direction indicated by the arrow, and

Fig. 3 is a cross sectional view on the line 33 of Fig. 1, looking in the direction indicated by the arrow.

Referring specifically to the drawings, wherein like reference characters designate like or similar parts, I provide a chronological strip member 4 and a chronological strip member 5, and preferably although not necessarily a chronological strip member 6. These members are disposed in parallel relation within a suitable casing, for instance that shown at 7, and preferably constructed of metal. The glass or other transparent panel 8 is disposed over the outer faces of the members 4, 5 and 6 and is preferably secured in place, as well as the members, by an inwardly bent overlapping and continuous flange 9. It will also be noted that the inner side edges of the members 4 and 6 as well as the side edges of the member 5 are inclined or beveled. This is desirable since as a; result the members 4 :and 6 will overlap the member 5 and thereby prevent the tendency of outward displacement thereof against the panel 8.

Member 4. has suitable designations or Specification of Letters Patent.

delineations at its outer face to represent the days of the weeks, and the designations are suliicient in number to represent the days of any month. The corresponding face of member 6 is delineated so as to merely represent Sundays, by the letters S although it may have any desired representations. Member 5 has numbers thereon corresponding to the days of the month and are adapted to register and coiiperate with the designations both of member 4 and member 6.

It will be noted that the member 5 is shorter than the members 4 and 6. Also members 4 and 6 are-preferably stationary while the member 5 is slidable and slides relatively to the members 4 and 6. While any suitable means may be employed to effect the sliding of member 5, yet flexible cords or the equivalent 10 and 11 may be provided respectively being connected to the member 5 at the top and at the bottom and extending through. and beyond the top and bottom ends of the casing to facilitate Inanipulation. Member 10 may have an eyelet 12 fastened thereto both to facilitate its manipulation and to afford a means to engage a nail, hook or other supporting element. These flexible members 10 and 11 are fastened to the strip 5 in any. suitable manner. The set screw is mounted in the strip 6 and in one side wall of the casing and is operable against one side of the strip 5 in order to tightly engage it and prevent accidental displacement. I

In use, according to the current month, strip 5 is moved longitudinally relatively to the strips 4 and 6 by manipulation of the cords 10 and 11 after loosening of the set screw 13. The numeral 1 should be brought into registry with the day of the week' on which the first day of the month occurs. The other numbers and days of the week will correspond for the entire month and by selectively considering the delineations of strips 4 and 5, the days of the week on which the different dates occur, and vice versa, may readily be determined. .As.wel.l by reference to strip 6 in connection with strip 5 it can readily be determined on what dates Sundays fall and what dates occur during the weeks in which the Sundays occur. After the strip 5 has been manipulated, set screw 13 may be again tightened so as to prevent accidental displacement of the member 5 relatively to members 4 and. 6. As

previously stated, the device as an entirety may be suspended from a nail,'hook or the equivalent by means of eyelet 12.

Since merely the preferred embodiment has been illustrated and described, it is to be understood that changes in the details of construction may be resorted to Within the spirit and scope of appended claim.

I claim A calendar comprising a casing having an open side with a surrounding flange, a transparent member within said casing and engaged with said surroundingi flange, spaced stationary strips within said casing and provided with oppositely beveled opposed faces,

amovable central strip provided with oppositely beveled longitudinal edges engaged with the beveled faces of said stationary strips, said stationary strips preventing displacement of said movable strip, one of said Copies of this patent may be obtained for five cents each, by addressing'the Washington, D. 0.

stationary strips having the days of the week arranged in chronological order upon its outer face, said movable strip having numerals arranged in chronological order upon its outer face to represent the days of the month, means connected with said movable strip to adjust the same with respect to said stationary strips for the different months'of the year, means mounted upon the last mentioned means for suspending said calendar upon a supporting means, and securing,

means for securing said adjustable strip in adjusted position.

In testimony whereof I afiix my signature in presence of two witnesses.
